目的:对肿节风的不同提取方法进行比较研究。方法:采用冷浸提取、渗漉提取、回流提取、连续回流提取、超声提取、微波萃取六种不同的方法进行提取,并对提取物的收率进行比较,同时以富马酸含量为考察指标进行含量测定。结果:采用六种不同的提取方法提取所得提取物的收率及有效成分的含量有较大的差异,其中回流提取及连续回流提取所得提取物的收率相对较高,而超声提取及微波萃取所得提取物中有效成分的含量相对较高。结论:与其它方法相比,微波提取法具有提取快速,节省时间、溶剂和能源,所提取的有效成分含量较高等优点。
Objective: To compare the different extraction methods of swollen wind. METHODS: Six different methods were used for cold extraction extraction, percolation extraction, reflux extraction, continuous reflux extraction, ultrasonic extraction and microwave extraction. The yield of the extracts was compared, and the content of fumaric acid was used as an indicator. Determination of content. RESULTS: There were significant differences in the yield of the extracts and the content of the active ingredients extracted by using six different extraction methods. Among them, the yields of the extracts obtained by reflux extraction and continuous reflux extraction were relatively high, and ultrasonic extraction and microwave extraction were used. The content of the active ingredient in the resulting extract is relatively high. Conclusion: Compared with other methods, microwave extraction method has the advantages of rapid extraction, saving time, solvent and energy, and high content of extracted active ingredients.
